[edit] Need
I-beam rigging clamps
- for training at Fire Hall
- sloped I-beams, flange 4 inches wide
- need to determine flange thickness
- exterior roof has 12 degrees slope; interior ceiling has 2 angles: the edges are greater, the center less (where we will be working)
- horizontal I-beams, flange approx 7-8 inches wide
- need to determine flange thickness
- more accurately measure flange width
-
[edit] Requirements
- adjustable from 4 to 8 inches
- placeable on sloping I-beam up to 12 degree slope
- non-rolling
- MBS: 40 kN
- 2 person load, SSSF, pulley at top
- = 8993 lbf
- WLL is not the same as MBS. It has a Design Factor (DF) built in for safety. That factor is not documented; OSHA talks about factor 2 in other parts of its standard. But without specification, we assume that the MBS is only negligibly greater than the WLL.
